The square column film-penetration connecting device is connected with a square column and a film material which penetrates through the square column, wherein film-stretching steel plates are circumferentially welded at the periphery of a film-penetration part of the square column; bolt holes are formed in the film-stretching steel plates at intervals; the film material has a double-layer curled edges close to edges of the square column, and an embedded rope penetrates through the double-layer curled edges and is close to one side of the square column; the double-layer curled edges are arranged on the upper surfaces of the film-stretching steel plates; a rubber pad is arranged between the double-layer curled edges and the film-stretching steel plates; a circle of film pressing steel plates provided with bolt holes are arranged on the double-layer curled edges; and the bolt holes of the film-stretching steel plates are corresponding to the bolt holes of the film pressing steel plates, and bolts penetrate through the bolt holes to fix the film material and the rubber pad among the bolts by clamping. The square column film-penetration connecting device realizes fixed connection of a film-penetration penetrating a variable cross-section straight square column or an inclined square column of a large-span film-tensioning structure, and the length of the film material can be adjusted by aiming at radian, wrinkles and the like of a film surface.
Description
Technical field
The present invention relates to the film material of a kind of construction equipment and construction of building membrane structure, particularly a kind of large span jacking membrane structure through device and the job practices of variable cross-section Nogata post or rhombic prism.
Background technology
In rope membrane structure field, jacking membrane structure is that film material supports by support column and steelframe, regulates stretching rope moulding.Because film material curve force analysis is complicated, structural column is worn film and is caused film surface stress to be redistributed, and makes node processing also very complicated.Domestic structural column is worn Membrane of Tensile Buildings precedent seldom.When a small amount of Structure of need post is worn film, existing processing mode is constructed according to following program:
Step 1: site operation is prepared, and steel work or other support systems have been constructed;
Step 2: Membrane of Tensile Buildings cloth machines, the aluminium sheet of wearing film node apparatus is ready to complete;
Step 3: aluminium sheet and film cloth fixedly complete;
Step 4: Membrane of Tensile Buildings cloth promotes in place successively, and connect into integral body;
Step 5: two times tensioning applies prestressing force to design load, and stretch-draw completes.
Because this technique is first fixedly to wear film node apparatus on film cloth, after the lifting of film cloth is in place, can directly carry out the stretch-draw of large area film material, once the shortcoming of this technique is square column is oblique placement or column with variable cross-sections, wear film node apparatus and cannot promote film cloth as installed before in place prior to film cloth, large span film material cannot regulate moulding radian according to field conduct situation, cannot make film material reach the prestressed setting of two times tensioning.
Summary of the invention
The object of this invention is to provide a kind of square column and wear film linkage, the technical problem that the film material that solves large span jacking membrane structure is fixedly connected with through the straight square column of variable cross-section or rhombic prism, solves the technical problem of film material length adjustment.
For achieving the above object, the present invention adopts following technical scheme:
A kind of square column is worn film linkage, be connected with the film material through square column with square column, described square column is welded with the film steel plate that stretches tight wearing the peripheral hoop in film place, on the described film steel plate that stretches tight, interval has bolt hole, described film material is double seam at the edge that approaches square column, in double seam, be installed with pre-buried rope, described pre-buried rope is near square column one side, described in described double seam is placed in, stretch tight film steel plate above, double seam and stretch tight and be lined with rubber pad between film steel plate, on double seam, being arranged with an astragal has the press mold steel plate of bolt hole, the bolt hole of the described film steel plate that stretches tight is corresponding with the bolt hole of press mold steel plate and be installed with bolt, film material and rubber pad are fixedly clamped betwixt.
The described thickness that stretches tight film steel plate is not less than 8mm, and width is not less than 100mm.
Under the described film steel plate that stretches tight, square column outside is welded with floor.
The both sides of edges of described film material is all lined with rubber pad.
Described square column is batter post or right cylinder.
Square column is worn a job practices for film, applies above-described square column and wears film linkage, and its construction sequence is as follows:
Step 1: site operation is prepared, and the support system of membrane structure has been constructed;
Step 2: complete position and the radian of caudacoria material by FEM Numerical Simulation stretch-draw, square column and film material intersection location and shape;
Step 3: according to computer simulation result processing of films material, and get the various materials of wearing film location node ready;
Step 4: the film material lifting of first film unit is in place, and order is installed the film material of adjacent membranes unit;
Step 5: after the whole installations of film material of film unit, square column is installed and is worn film linkage: the good rubber pad of both sides of edges pad of film material, make pre-buried wire clips in one end of rubber pad, rubber pad both sides are clipped in stretches tight between film steel plate and press mold steel plate, bolt through stretching tight the bolt hole of film steel plate and the bolt hole of press mold steel plate, is fixedly clamped film material and rubber pad respectively;
Step 6: the pre-buried rope of stretch-draw makes all film units be linked to be an integral body, controls stretch-draw amount face is tightened, and keeps face radian smooth, and finally determines that film material, through the length after bolt, carries out at twice stretch-draw and reaches designing requirement;
Step 7: cannot carry out the film location of wearing of FEM Numerical Simulation, the film material length being installed with after bolt by adjustment is carried out local modulation, eliminates stress and concentrates the face fold causing;
Step 8: by the precalculated position of film Plate Welding in square column outside of stretching tight, itself and square column are fixed.
Compared with prior art the present invention has following characteristics and beneficial effect:
The film material that the invention solves large span jacking membrane structure is through the technical problem of variable cross-section square column or oblique square column node, and the large area film material of can accomplishing first to construct, then according to stretch tight the at the scene welding of film steel plate of the size of square column.Then according to scene, need to the radian of face, fold etc., carry out the adjusting of film material length, make film material reach the prestressing force setting of two times tensioning.
The present invention can be widely used in large span jacking membrane structure through the construction of variable cross-section Nogata post or rhombic prism.
